Article
Full-text available
The behaviour of five different water-based anticorrosive paint systems for the corrosion protection of carbon steel surfaces was evaluated by electrochemical impedance spectroscopy (EIS). Epoxy-polyamine, epoxy-amine and epoxy-acrylic resins as primer coats, and acrylic-polyurethane and acrylic paints as top coats, were investigated both in single...

The associative effect towards the corrosion of AISI 304 stainless steel caused by the main two bacterial species present in marine environments around the Canary Islands (Spain) has been investigated using electrochemical techniques. The test environments were sterile conditions, with SRB (sulphate-reducing bacteria) Desulfovibrio desulfuricans (s...
Article
Full-text available
Simulation of the effects of natural atmospheres on metals using electrochemical techniques together with accelerated tests presents certain characteristics that make it highly interesting from the point of view of the study and prediction of corrosion. It will enable us to forecast the behavior of a metal exposed to a particular environment withou...
Article
A comparative study has been undertaken on the behaviour of AISI 304 steel in Postgate medium with and without the presence of Desulfovibrio desulfuricans subspecies desulfuricans bacteria (strain DSM 642). Electrochemical studies were carried out with open circuit potential measurements, linear polarization, electrochemical impedance spectroscopy...
Article
Green rust 2 (GR2(SO2−4 )) was detected amongst the products formed on a carbon steel rod exposed to atmospheric corrosion using X-ray diffraction (XRD). The presence of green rust 2 has been related to sulphate reducing bacteria (SRB) in the sea spray. These were detected using test catch rods made out of inert material and posterior lab identific...
Article
A comparative study of the electrochemical behaviour of stainless steel AISI 304 plates immersed in a natural seawater hopper and, under lab conditions, in sterile natural seawater, were carried out over seven weeks. The behaviour of these plates was, likewise, studied in seawater plus sulphate reducing bacteria (SRB) isolated from the natural seaw...
Article
The layer of corrosion products forming on zinc in atmospheric environments of varying aggressivity have been characterised and compared with previous results obtained for carbon steel. The characteristics of said layers have been linked to the nature of the products found. Likewise, we have found that EIS is a useful tool towards characterising th...
Article
The following paper proposes a tertiary treatment system for the recycling of wastewater to be used as irrigation water for crops such as the banana tree that require water of a high quality. A physical-chemical system is proposed followed by Electrodialysis Reversal (EDR) desalination. The aim is to lower the overall levels of chlorides and dissol...
Article
Carbon steel, copper, zinc and aluminium test pieces were exposed to a large variety of environmental conditions in a reduced geographic area close to the coastline in order to ascertain the degree of deterioration of the same due to environmental corrosion. Calculations of corrosion rates were made via loss of weight (in the case of carbon steel,...
Article
A study was carried out in order to identify the various elements which make up the layer of rust which is produced on carbon steel exposed to the atmosphere in the province of Las Palmas (The Canary Islands, Spain). XRD and SEM analyses were used in order to identify and describe the various corrosion products produced over different areas on the...
Article
The properties of the corrosion products for carbon steel were characterized using the data from 39 corrosion stations in varying environments (urban, rural, marine and marine-industrial) in the province of Las Palmas (The Canary Islands, Spain) using electro-chemical impedance spectroscopy and the gravimetric method via mathematical data modelling...
Article
This study presents results obtained in the characterization of corrosion undergone by test samples of zinc in the presence of chloride and sulfate ions using electrochemical techniques (Tafel and Ecorr vs t). A simulation is presented for the major polluting agents in the Canary Island's atmosphere. The SO42- anion which is the intermediate produc...
Article
This article presents results obtained on the determination of atmospheric corrosion of copper in the province of Las Palmas (Canary Islands, Spain). It was shown that levels of corrosivity obtained for copper exceeded the upper C5 limit specified in the ISO 9223 norm at many stations. For this it is suggested that this norm be incorporated into a...
Article
This article presents results on the study of atmospheric corrosion of zinc in the Las Palmas province (Canary Island, Spain). Very high rates of corrosion were observed, in many cases exceeding the C5 limit specified by international norm ISO 9223. Chloride ion is found as the main causing factor for these high rates of corrosion, together with th...
Article
This paper presents the results of the electrochemical measurements regarding the epoxy films electrodeposited on carbon steel. Nyquist and Bode diagrams were recorded for various immersion periods in 3% NaCl solution, using the open circuit potential method; their interpretation allows us to modell the corrosion process of carbon steel substrate u...
Article
Copper sample were exposed (for 1 year) in different areas of Fuerteventura Island from Canare Archipelago, to study atmospheric corrosion in this tropical climate. The chlorine and SO 2 concentrations were determined; also the moisture content was measured all exposure time. The corrosion products were analysed by X ray diffraction. The copper cor...

The anodic behavior of a ternary titanium Ti-15Mo-5Al alloy in comparison with the base metal and the binary Ti-15Mo alloy in concentrated acid solutions of 10% H2C2O4, 30% and 40% H2SO4, 10% HCl is presented. The impedance spectroscopy and potentiodynamic technique were used in order to establish the effects of alloying elements. In concentrated H...
